blender (2.92 BETA) liquid simulation with viscosity becoming really stretched on one side
Because you are too close to a Domain border and since you have set collide with all sides of domain it probably stick to it.
When I move it at center it seems to be fine.

Consider if Domain dimension 28 m is necessary. For realistic result is better to work with real size. To avoid possible issues Apply Scale Ctrl+A to all simulation participant to get them all at scale one.
